I believe that is the nucleus, if so the answer is D) Genetic Information. The nucleus carries chromosomes that are composed of DNA that carry genetic information.
Once they understood the structure of DNA a lot of things became more clear including how DNA was replicated.
So I think your answer is copies? meaning how it is copied (replicated).
The structure also led later on to how it was transcribed into mRNA (and eventually into proteins by ribosomes).
Answer:
Bacteria commonly change <u>nitrogen</u> to a form that can then be easily assimilated by plant.
Photosynthesis occurs in the chloroplast, an organelle specific to plant cells.
All organisms share a common ancester: humans share a common ancestor with E. coli; E. coli share a common ancestor with an oak tree; humans share a common ancestor with an oak tree.
<span>If I hypothesized the two organisms shared a recent common ancestor, they I would predict that their genomes would be highly similar. For example, their genomes would contain about the same number of bases, and the base sequences (especially of protein-coding genes) would be highly identical.</span>
